I've attached the config.bin from my T28 running RPS 2.72.0.31.

I can also definitely confirm my suspicions above. If I go to the account page and set the SIP Server 1 -> Server Expires timer to a higher value (say 3600), then the phone backlight will only come on once per hour (3600 - my 100 seconds min. session time on PBX). If I leave it at 180, it comes on every 80 seconds (180 - 100 seconds min. session time on PBX).

If the account is not registered the backlight stays off.

So seems like it should be an easy fix, just don't turn on the backlight if registration response from a server that is already registered to...

Thanks!
